HARVESTER.

SPECIFICATION forming part of Letters Patent No. 241,498, dated May 17, 1881.

Application filed February 12, 1881. (N0 model.)

To all whom it may concern Be itknown that I, CHRISTOPHER W. LEVAL- LEY, a citizen of theUnited States of America, residing at St.Paul, in the county of Ramsey and State of Minnesota, have invented certain new anduseful Improvements in Harvesters; and I' do herebydeclare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art towhieh it appertains tomake and use the same, reference being had to the accompanying drawings, and to'letters or figures of reference marked thereon, which form apart of this specification. Figure 1 is afrontelevation of aharvester to which my improvements are applied. Fig. 1 is a detached viewppartly in section, of the mainaxle and a portion of thedevices connected therewith. Fig. 2 is a detached view, showingthe adjacent ends of the elevator-belts, and the carrier-belt, which is arranged in rear of the cutting apparatus. Fig. 3 is aplan or top view of the harvester, the elevator having been removed therefrom in order to more clearly show the gearing. Fig.4is a view of the main supporting and driving wheel, taken from the stubble end of the-machine, the other portions of the frame having been removed. Fig. 5 is a view of the driving-gear of the harvester, taken from the stubble side, on the dotted line 00 00, Fig. 3. Fig. 6 is a view of the shaft and its pinion, and a ratchet employed for raising the machine upon thedriving-wheel. Fig. 6 is a detached View of a wheel mounted on the main axle, taken from the grain side of the machine. Fig. 7 is a viewof the grain-wheel and its supporting attachments, from the grain side of the machine, the hub and part of the spokes being removed. Fig. 7 a is atop or plan view of the sameparts. Fig, 8 is a view detached of the devices employedfor supporting the grain end of the machine upon the grainwheel. Fig. 9 is aview of the reel-shiftin g devices. Fig. 10 is a top view of Fig.9,and Fig. 11 is a section of the shifting-lever and clamp. This invention relates to an improvement upon a machine organized substantially like that patented to me February 6, 187 7 and having applied thereto the binder patented to me April 27, 1880.

In the drawings,'A A are the front and rear nal bar.

longitudinal bed-pieces of the frame. A A A are cross-girts. A and A? are front supporting-posts, and A the horizontal longitudi- B is the axle of the main drivewheel B.

I will now describe the mechanism for supporting one end of the machine upon the main drive-wheel B.

Referring to Figs. 1, 3, 4,5, and16,O is a segmental yoke attached totheinneriface of .cross-girt A bymeans-of flanges 0,.and provided upon one of its inner faces with asegment of cogged gear, 0. O is a similar yoke or frame attached to cross girt A by means of flanges c and likewise provided with a segrack 0 1B is a gear-wheel, the cogs of which are arranged tangential to a circle within, and concentric wiith the circumference. instead of radial to the center. (See Fig. 6

b" is a bearing=block mounted loosely upon axle B, and-fitted to receive the inner end of a shaft, B which carries a pinion, b adapted to mesh with the cogs of wheel B The outer or rear end of shaft B is mounted ina rear girt, A, or in a bearing at 11 Fig. 4, attached thereto, and carriesa ratchet-wheel, N, which is actuatedby a vibrating pawl, 11. The bearing Ifhas a loop or bracket rising therefrom, serving as a stop to limit the throw of the pawl b4. The extreme outer end or rear end of shaft 13 is squared, as at I), so as to receive a wrench, and by examining Figs. 1,3, 4, 5, and 6, it will be understood that by rotating shaft 13 the gear-wheel B and pinions b and b may be rotated in either direction, whereby the stubble endof the machine may be raised or lowered upon the 'main drive-wheel B, and locked at the desired height by means of the pawl'b As shown in Fig. 1, the pinions b b care-each provided with flanges upon their outer faces, projecting as far as or a little beyond the outer ends of the cogs, the pinions being placed at such-distance apart on the axle B that these flan ges shall run in close contact with the outer faces of the yokes or frames 0 0, thereby supporting these yokes against spreading, this be- IOO ing especially desirable when the machine is running over rough ground and is lurched from side to side. r

d is a secondary shaft carrying a pinion, D, which latter is rotated by a wheel, D, keyed to shaft B. A clutch at d, of suitable char acter connects wheel D with shaft (1. They may be disconnected by means of a lever, (2*.

D is a bevel-wheel on shaft, d, meshing with with pinion d on the crank-shaft D from which devices motion is imparted to the various parts of the machine. (1 is an adjusting-link engaging at one end with a head, (1 ,011 shaft B, and at the other with a head, D which surrounds shaft d. By these parts the depth of mesh between wheels D and D may be regulated, as required, when the frame is raised or lowered 0n wheel 13.

d is a spur-pinion on shaft (1 rotating wheel d keyed to shaft d This shaft al is mounted on girt A and carries a sprocket-wheel, d,

which drives the sprocket-wheel h. The latter wheel conveys power to the reel-shaft by a tumbling-rod, H E.

It will be seen that the chain connecting sprockets d and h need not be varied in length to conform to different vertical positions of the machine.

H H are reel-bearers pivoted to standards 9 g, which rise respectively from the gearplank G and post G.

G is a rock-shaft mounted on the frame of the machine and connected with the rear ends of the bars H H by links g 9 Said links are pivoted at the upper ends to the bars H H and at the lower ends to crank-arms g projecting from shaft G G is a lever which is connected with rockshaft G It carries a pawl which engages with a ratchet, 9, attached rigidly to the sh aftsupport. By means of lever G arms H H can be vibrated on their pivots and the reel can beraised or lowered.

I l. are bars on the inner sides respectively of the bars H H. They each carry a cogged rack, 6 which engages with a cogged pinion, i.

I is a shaft connecting and keyed to the pinions t" and mounted in the rear ends of the bars H H.

M are clasps or yokes which hold together the rear ends of bars 1 and H and I and H respectively.

I is a lever pivoted to the reel-bearer and connected with the end bar, I, by a link, I,

shown a construction of reel-bearers and sliding-bars closely resembling the corresponding parts in this case, except that in my earlier patent the bearers are each made in one piece and slotted. at its front end, whereas in this latter construction the slot is formed by means of a metal strap, H which is not only a cheaper but more durable construction, and the device I i i is a much better contrivance for shifting the position of the bars I I and the reel than is the device shown in my earlier patent.

I am aware, also, that the reel of a harvester has been heretofore revolved by means of a chain passing underneath idler-pulleys mounted near the front edge of the machine and running thence to a driving-sheave on the secondary shaft or counter-shaft; but I regard the construction and arrangement of parts which I have shown, including the mounting of the drivingsheave h on the stationary arm or bracket H and the connecting of said sprocketwheel with the reel-shaft by means of the tumbling-rod, as being much better, because this construction not only permits the reelto be moved forward and backward, but also up and down, without increasing or diminishing the tension of the driving-chain.

I is a thumb-nut which clamps the lever I against the reel-bearer H, and by this nut the lever may be held in any desired position.

H is a stay-rod connecting the reel-bearer H with the stationary frame. It braces the reel and prevents endwise swaying thereof. It is loosely connected both to the reel and to the frame, so as not to cramp any of the parts in whatever position the reel may be.

E is the grain-wheel on shaft E.

E. c c c c are soeketed ears cast preferably in one piece with wheel E and e is a sleeve projecting outwardly from said wheel. The shaft E passes loosely through slot fin plate F, which latter is secured to the machine. The plate F has a vertical way, f, in which fits the head 0 of shaft E. Said plate has also a cogged rack, f cast therewith, which rack meshes with wheelv E.

F is a pawl pivoted on shaft E behind wheel E. It engages with rack f and is prevented from swinging downward too far by means of a lug,f", projecting through slotf.

By means of a leverinsertcd in either of the sockets c the operator can rotate pinion E and raise and lower the grain end of the machine and lock it in any desired position by the pawl F and rack f What I claim is- 1. The combination, with the grain-wheel and the slotted plate F, of the pinion E socketed plate a c 0, provided with sleeve 0 the pawl F, provided with 1n g f, and the shaft or stud-axle E, substantially as set forth.
